What reviewers say
“Vinho com boa complexidade. Recomendo que abra a garrafa e tome sem pressa pois com certeza a diferença da primeira para a última taça é bem evidente (todas valendo a pena tomar). Cor vermelho rubi com halos sem muito sinal de envelhecimento (safra 2019 bebido em 2024).”
From a top-rated Vivino review for this bottle.
Summary
From San Rafael in Argentina, Alfredo Roca Parcelas Originales Old Vines Tinto is a red. It blends Malbec, Cabernet Sauvignon, Bonarda and Shiraz Syrah.
341 Vivino reviewers rate with enough spread for a personal baseline to be measured, and those are the ones the calibrated score reads; a separate, broader pool of 351 reviewers with at least two ratings each feeds the raw-average track. Its in-cohort standing is measured against 481 other reds from Argentina, not against the corpus as a whole.
How the score was built
We compare the reviewers of this bottle against every other wine those same people reviewed. Each review is scored relative to the reviewer's own baseline — four stars from someone who hands out fives means something very different from four stars from someone who rarely goes above three. Every reviewer then counts the same, so the result is a calibrated consensus rather than a star average.
- Global percentile
- Where Alfredo Roca Parcelas Originales Old Vines Tinto lands against every wine we rank.
- In-cohort percentile
- The same comparison narrowed to its cohort — wines of the same type from the same country. A Chilean red is judged against Chilean reds, not against Champagne. Ranked against Red · Argentina (482 wines).
- AI-adjusted percentile
- The same reviewer-normalized score, corrected for how much confidence the sample supports: thin samples are pulled toward the corpus average. Each wine keeps the share n / (n + 53) of its measured distance from the average, where n is its calibrated-reviewer count, and the result is ranked on the same scale as the global percentile.53 is the median sample size across everything we rank. Here n is 341.
